Is caramelo e150d vegan?

Caramelo e150d is the Spanish and Portuguese label term for caramel IV, also known in English as sulfite ammonia caramel. It is a widely used brown food coloring produced through the controlled heat treatment of carbohydrates in the presence of both sulfite and ammonium compounds. The starting carbohydrates are sourced from plant crops, typically corn, wheat, or sugar beets. This additive is commonly found in dark-colored foods and beverages, including colas, beer, soy sauces, commercial gravies, and baked goods.

This ingredient is vegan because its source materials and processing agents are entirely plant-based and mineral or synthetic. The sugars utilized are botanical in origin, and the chemical catalysts used to achieve the dark color are inorganic compounds rather than animal derivatives. Because no animal tissues, animal byproducts, or animal-derived processing aids are used during its manufacture, caramelo e150d is suitable for vegans.
